Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall and door guards used in high-traffic areas are typically made from polluting materials that harm the environment, such as vinyl and plastics containing hazardous chemicals, and lack eco-friendly alternatives for durable protection.
Innovation Solution
A composition combining biopolymeric components like polylactic acid (PLA) and polyethylene terephthalate glycol (PETG) with a modifier, which is used to create a durable, environmentally friendly material for molding wall and door guards, reducing the use of fossil fuels and greenhouse gas emissions, and eliminating harmful substances like halogens and lead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional vinyl or plastic materials are used to construct wall and door guards, then durable protection is achieved, but environmental pollution and harmful chemical emissions occur
Solution Approach 1:
The patent uses a composite material system consisting of thermoplastic polymer granules (60-80% by weight), biopolymer granules (10-30% by weight), and compatibilizer granules (5-20% by weight). This composite approach combines the durability of conventional plastics with the environmental benefits of biopolymers, resolving the contradiction between protection durability and environmental pollution.
Solution Approach 2:
The patent changes the chemical composition parameters of the material by incorporating biopolymer content (10-30% by weight) and specific compatibilizers, transforming the material from harmful conventional plastic to an environmentally friendly composite while maintaining protective functionality.
2Object-generated harmful factors
If biopolymer materials are used to construct wall and door guards, then environmental friendliness is improved, but material durability and protective capability may be reduced
Solution Approach 1:
The patent creates a composite where biopolymer granules (10-30% by weight) are combined with thermoplastic polymer granules (60-80% by weight) and compatibilizer granules (5-20% by weight). This composite structure allows the biopolymer to provide environmental benefits while the thermoplastic matrix maintains the structural durability needed for protection.
Solution Approach 2:
The compatibilizer granules (5-20% by weight) act as an intermediary between the biopolymer and thermoplastic polymer phases, improving interfacial adhesion and ensuring that the biopolymer reinforcement effectively enhances durability without compromising protection capability.
3Reliability
If hazardous chemicals are used in material production, then material performance is achieved, but chemical safety and environmental compliance deteriorate
Solution Approach 1:
The patent changes the material composition parameters by specifying thermoplastic polymers with melting points of 160-260°C and incorporating biopolymers with specific glass transition temperatures, eliminating hazardous chemicals while maintaining material performance through controlled physical parameters.
Solution Approach 2:
The patent converts the potential weakness of biopolymers (lower durability when used alone) into a benefit by using them in controlled quantities (10-30% by weight) within a composite system, where they provide environmental benefits without compromising overall material performance.

AI summary
The invention relates to a composition for use in the production of an article of manufacture, and in particular, to the manufacture of wall and corner guards. The composition includes a biopolymer in combination with PETG as well as a modifier. The biopolymer and modifier are preferably produced from an annually renewable source such as corn or sugar as opposed to traditionally used petroleum based plastics. In this manner, the composition of the invention is relatively environmentally friendly as compared to known compositions while maintaining many of the desirable qualities thereof. In addition, the production of the articles of manufacture results in the consumption of fewer fossil fuels and less production of pollutants.
